It should be understoodthat the specific embodiments described herein are for the purpose ofillustration and explanation of the present disclosure, and are notintended to limit the disclosure.

As shown in FIGS. 1-4, a cigarette mouthpiece for an electroniccigarette is provided in the present disclosure. The cigarettemouthpiece comprises a hard substrate 10. A soft substrate 20 is mountedon the outside of the hard substrate 10. In one embodiment, the hardsubstrate 10 is made of one of a group of hard plastic, stainless steeland glass. It can be appreciated that the hard substrate 10 can be madeof other hard materials to support the soft substrate 20. A through hole(not shown) is defined inside the hard substrate 10 and extends throughtwo opposite ends of the hard substrate 10. The through hole is mainlyconfigured as a smoke passage when the user inhales. It can beappreciated that the electronic cigarette is an automatic electroniccigarette and an independent inductive passage can be defined inside thethrough hole.

In one embodiment, the hard substrate 10 having an approximately flatshape comprises a top end 11 and a bottom end 12 opposite to the top end11. The bottom end 12 is relatively wider than the top end 11 and isconfigured to connect to a main body 31 of a cartomizer. The bottom end12 can have any shape, such as a rectangular parallelepiped shape or acylindrical shape. In one embodiment, the bottom end 12 is detachablyconnected to the main body 31 by clamping or screwing. It can beappreciated that the fixed connection, such as snap fit connection, isalso applicable. In this embodiment, the cigarette mouthpiece and themain body 31 are fixed together via a latching structure 19. In thisembodiment, the top end 11 has a rectangular parallelepiped shape. Itcan be appreciated that, the top end 11 can have any shape, such as acylindrical shape or an ellipse cylinder shape.

A concave portion 18 is defined on the hard substrate 10 and locatedbetween the top end 11 and the bottom end 12. In one embodiment, thereare two concave portions 18. The two concave portions 18 are located onthe front side and the rear side of the hard substrate 18, respectively.In one embodiment, each concave portion 18 defines a groove 14. When thesoft substrate 20 is mounted in the groove 14, the outer surface of theentire concave portion 18 becomes a smooth curved surface accordingly.

A through hole is defined inside the hard substrate 10 and extendsthrough the top end 11 and the bottom end 12. Smoke outlet 17 is theopening of the through hole located at the top end 11.

When the user inhales, the smoke can be sucked off from the smoke outlet17. The lips of the user contact with the soft substrate 20, and theuser can obtain comfortable tactility.

The soft substrate 20 can be made of elastic materials. The appropriateelastic material can be selected from one of a group of silicone resin,latex, thermoplastic elastomer (TPE), ethylene-vinyl acetate copolymer(EVA) and soft silicone rubber. It can be appreciated that other softand environmentally friendly materials are also applicable.

Both of the opposite sides of the hard substrate 10 define a groove 14,and the two soft substrates 20 are mounted in the corresponding grooves14 respectively.

In one embodiment, the soft substrate 20 is a sheet. Specifically, softsubstrate 20 has a shape selected from one of a group of circular,square and ellipse. Furthermore, the two ends of the soft substrate 20are relatively thinner than the middle portion of the soft substrate 20.The shape of the groove 14 is configured to fit such soft substrate 20.

In one embodiment, the soft substrate 20 is melted at a high temperatureand then adhered to the groove 14.

As shown in FIG. 5 and FIG. 6, in one embodiment, the soft substrate 20is disposed around the hard substrate 10. That is, the soft substrate 20has a sleeve shape and is sleeved on the outside of the hard substrate10. In one embodiment, a retaining protrusion 13 is defined on theconcave portion 18, and a retaining hole 21 corresponding to theretaining protrusion 13 is defined on the soft substrate 20. Theretaining protrusion 13 inserts into the retaining hole 21 to preventthe soft substrate 20 from slipping.

It can be appreciated that two retaining protrusions 13 configured toretain the soft substrate 20 can be defined on the outside of the hardsubstrate 10 along the circumferential direction of the hard substrate10. One retaining protrusion 13 is adjacent to the top end 11, and theother retaining protrusion 13 is adjacent to the bottom end 12. The softsubstrate 20 is located between the two retaining protrusions 13.

As shown in FIGS. 7-9, in another embodiment, the hard substrate 10 hasan approximately cylindrical shape and comprises an upper section 15 anda lower section 16. The diameter of the lower section 16 is larger thanthat of the upper section 15. A through hole is defined inside the hardsubstrate 10 and extends through the upper section 15 and the lowersection 16. The top end of the through hole is the smoke outlet 17. Agroove 14 is defined on the outside of the upper section 15 along thecircumferential direction of the upper section 15. The soft substrate 20is mounted on the outside of the upper section 15 along thecircumferential direction of the upper section 15. Specifically, thesoft substrate 20 has a sleeve shape and located in the groove 14. Whenthe soft substrate 20 is mounted in the groove 14, the outer surface ofthe entire upper section 15 becomes a smooth curved surface.

In one embodiment, there is no concave portion 18 defined on the hardsubstrate 10. That is, between the top end 11 and the bottom end 12,there is no curved surface or planar surface defined inclining to thecentral axis of the cigarette mouthpiece. Furthermore, the shape of thehard substrate 10 is selected from one of a group of cylinder, frustumof a prism and frustum of a cone. Furthermore, a groove 14 is defined onthe hard substrate 10, and the soft substrate 20 is mounted in thegroove 14. Alternatively, there is no groove 14 defined on the hardsubstrate 10, and the soft substrate 20 is directly mounted on the hardsubstrate 10.

In one embodiment, the connection method between the soft substrate 20and the hard substrate 10 includes, but is not limited to, adhesion andsleeving.

In one embodiment, a cartomizer is provided. The cartomizer comprises amain body 31 and a cigarette mouthpiece mounted on the top end of themain body 31. A liquid storage chamber is defined in the main body 31.The cigarette mouthpiece is any one of the cigarette mouthpiecesdescribed in the previous embodiments.
